Hesitating and stalling from dead stop
I have a 2000 Expedition that hesitates and sometimes stalls when taking off from a dead stop. The problem is not consistant and therefore hard to diagnose. I have had it to the dealership and two other mechanics and none of them have been able to fix the problem. So far they have replaced the intake gasket, fuel filter, EGR and PCV valves and have changed the PFE sensor and connecting lines. It seems they are just throwing parts at the problem and haven't a clue what is wrong. There are no error codes in the computer. So far I have spent around $1,500 on this problem and it is not any better from when I started and it might actually be a little worse. I seem to think the problem is in the fuel system and not electrical because all lights and gauges function normally when the problem happens. I can also sometimes produce the hesitation by shifting the transmission into second gear while going around 50 mph then giving it a good bit of throttle after the engine revs. Does anyone have any ideas what could be going on.
